The Contractor assumes all liability for damage and/or injury for use of chemical products or equipment. All chemicals shall be purchased and applied by properly licensed personnel. 1.1.6 Environmental Protection The Contractor shall provide a Spill Plan in the event cleanup efforts are required to protect rivers and drainage ditches from chemical contamination, sediment run-off, construction debris, and other damage. Soil erosion and sediment control provisions and maintenance in accordance with local requirements are required. In the case of a spill or release of any sort, the Contractor shall immediately notify the COR. Environmental Protection Plan (EPP). Contractor shall provide an EPP as a component of their technical proposal package. The written plan must outline strict procedures for managing refrigerants, handling hazardous waste, preventing spills, and ensuring compliance with federal environmental regulations such as EPA (Environmental Protection Agency) Section 608. 1.2 Quarterly PM Tasks For PoolPak Dehumidifiers, RTUs, and Mini-Splits, the contractor shall inspect and replace air filters as specified in the filter schedule, clean condensate drain pans, and flush drain lines to prevent blockages. The contractor must also calibrate thermostats, humidity sensors, and CO2 sensors against a certified reference, and inspect fan belts for wear, fraying, and proper tension, adjusting as necessary. For Exhaust Fans, quarterly maintenance includes lubricating fan and motor bearings, cleaning fan blades and housings of dust and debris, and verifying the operation of motorized dampers and louvers. For Boilers and Water Heaters, the contractor shall visually inspect for water, gas, and flue -- 2 of 14 -- 3 leaks, check system water pressure, verify the operation of the pressure relief valve, and document any operational error codes. For Boiler Circulating and Glycol Pumps, tasks include lubricating pump and motor bearings, visually inspecting for seal leaks, and checking for unusual noise or vibration during operation. 1.3 Semi-Annual PM Tasks Semi-annual tasks for PoolPak Dehumidifiers, RTUs, and Mini-Splits require the contractor to thoroughly clean evaporator and condenser coils with a manufacturer-approved, non- acidic cleaning solution. The contractor shall also check operating refrigerant pressures and temperatures, verify proper refrigerant charge, inspect compressor oil levels where applicable, and test all system safety controls and electrical safeties. For Exhaust Fans, the contractor must measure and record motor amperage and compare it to the nameplate rating. For Boilers and Water Heaters, the contractor shall perform a complete combustion analysis using a calibrated analyzer to adjust gas pressure and airflow for optimal efficiency and safety. This includes cleaning and inspecting burners, pilot assemblies, and flame sensors, and testing all safety controls such as high-limit, rollout, and spill switches. Heat exchangers must be inspected, cleaned, and descaled if necessary based on water quality and performance. For Boiler Circulating and Glycol Pumps, the contractor shall measure and record motor amperage and voltage. 1.4 Annual PM Tasks Annually, for all systems, the contractor shall conduct a comprehensive structural corrosion audit, inspecting all unit casings, ductwork, fasteners, and support hangers for rust and chemical degradation, documenting findings, and…
